TLDR
In this article, a variety of cement-stabilized rammed earth pullout test samples were fabricated with deformed, galvanized deformed and plain, and stainless steel rebar.Abstract:
Stabilized rammed earth offers a low energy durable alternative to conventional building materials, such as masonry and processed timber, for low-rise residential projects. To date, rammed earth construction has mainly been used in the developing world, particularly Africa and Asia. Despite recent applications in Australia and the United States, further development of rammed earth in these countries has been hindered by a lack of data on important aspects of material performance. In this paper, work undertaken to assess bond of rebars embedded in rammed earth is described. A variety of cement-stabilized rammed earth pullout test samples were fabricated with deformed, galvanized deformed, plain, and stainless steel rebar. Pullout bond resistance is shown to be a function of rammed earth compressive strength, rebar type, embedment length, and the method of specimen preparation.read more

Assessing the anisotropy of rammed earth
TL;DR: In this article, the authors present the first study of the anisotropic nature of rammed earth, carried out on two scales: the first is the scale of Representative Volume Elements (RVEs) of the material, with dimensions close to those of the walls on site, manufactured and tested in the laboratory.

Feature Importance of Stabilised Rammed Earth Components Affecting the Compressive Strength Calculated with Explainable Artificial Intelligence Tools
TL;DR: This work uses three machine learning regression tools, i.e., artificial neural networks, decision tree, and random forest, for predicting the compressive strength based on the relative content of CSRE composites (clay, silt, sand, gravel, cement, and water content).

Analysis of Bond Stress Distributions in Pullout Specimens
TL;DR: In this paper, the results from pullout tests, push-in tests, and a combination of pullout and pushin tests were investigated and it was shown that a suitable combination of pushout and pullout forces can simulate a nearly uniform bond stress distribution with ratios of maximum to average bond stress of 1.10 and 1.11 for pullingout and splitting failures, respectively.
